I've had this issue for a few months intermittently and with the coming of the warm weather it's bugging me more and more. The climate control in my 08 4.4 HSE will turn itself on while I'm driving and it's annoying the hell of of me. It'll always turn on to whatever setting I left it on before I turn it off but usually within a minute or within seconds of hitting the 'off' button it'll come right back on. I appreciate the initiative and all that but sometimes I just want to just drive with the windows down without having to finger fight this thing into submission. Anyone dealt with this? I can't find any info on it.
